AnkiDroid uses git history as the authoritative record of authorship. You own the copyright of your contributions, regardless of the copyright header. Copyright headers are optional
Please contact the maintainers, or raise an issue if you have any questions/concerns.
You may add a copyright header to work which you have created or nontrivially modified. Your name may be a pseudonym, and the email is optional.
The copyright line should be added at the end of the header and it is recommended to be formatted as follows:
// SPDX-License-Identifier: GPL-3.0-or-later
// SPDX-FileCopyrightText: 2023 Existing Contributor <email@example.com>
// SPDX-FileCopyrightText: 2026 New Contributor Name <email@example.com>
package com.ichi2.ankiAlternate formats are listed: https://reuse.software/faq/#copyright-symbol
You may request this header be added to your work retroactively (ideally via a pull request).
The project adds a collective copyright line to .kt files for license-compliance tooling:
SPDX-FileCopyrightText: Contributors to the AnkiDroid project
